The LDG Z-817H provides semi-automatic antenna tuning across the entire HF spectrum plus 6 meters, at power levels up to 75 watts. It will tune dipoles, verticals, Yagis, or virtually any coax-fed antenna. It will match an amazing range of antennas and impedances (up to 10 to 1 SWR), far greater than some other tuners you may have considered, including the built-in tuners on many radios.

The LDG Z-817H is similar to previous LDG tuners, but is specially engineered to integrate with your Yaesu FT-817 HF radio and external amplifier. The LDG Z-817H connects to the ACC port or sometimes called CAT (Computer Automated Transceiver) port on the back of the radio. The CAT interface allows an external device such as a PC or the LDG Z-817H to control the FT-817 by sending it serial commands. The LDG Z-817H takes advantage of this interface to simplify the tuning process -- one button push is all that is needed in order to switch the radio to PKT mode, transmit a carrier, read the transmit frequency, and then restore the radio to its previous mode and power level! Additionally, the LDG Z-817H is powered by internal batteries, so no extra power cable is needed.

Specifications:

0,1 to 75 watts SSB and CW peak power, 50W on digital modes and 6 meters. 50W max when used with non-FT-817 radio.

Will also work with non-FT-817 radios, but without automation of the radio.

Pass-thru CAT port allows Z-817H to control the FT-817 over the CAT bus while still allowing a host PC to also control the radio. Also permits seamless integration with Tokyo Hi Power HL-45B amplifier.
